Father's Day followed close on the heels of Alice's birthday celebrations, but the kids never tire of helping open presents.
Sometimes I get Zac a toy he wants "for the kids" but by getting it for him, it makes sure no kid lays claim to it and they have to share. It's a good way to provide mutual toys. Although, really, after a couple of days, original ownership is usually forgotten anyways.
A couple days later they went down to the pond to try out the boat.
It worked well, the battery lasted a long time, and the kids got pretty good at driving it.
